mccain spoke on cnn. >> first of all, the brutality depicted there is very disturbing. the moral of the story is that torture does not work. it is hateful, it is harmful, incredibly harmful to the united states of america. and to somehow make people believe that it was responsible for the elimination of osama bin laden is in my view unacceptable. >> reporter: mccain and democratic senator dianne feinstein, who heads the senate intelligence committee, sent two letters to the acting c.i.a. director, demanding to know what information the agency had provided the filmmakers. at a washington d.c. screening tuesday night, protestors dressed as detainees outside the newseum showed their objections, while inside, the filmmakers, who have said they deplore torture, told the "newshour" the dramatized account was intended to highlight an extraordinary intelligence effort. >> everybody's entitled to their opinion and there's certainly a moral complexity to that ten- year hunt but what i'm most proud of is that the film sheds light on the professionals in the intelligence community
